Ok, thanks for your answer, i’ll make a copy of the disk. I tried smartmontools as you suggested but it tells me that my disk doesn’t have SMART capacity which is weird.
Here is the result:
sudo smartctl -i /dev/sda1

I tried the -T permissive argument with no success.
I also ran hdparm in order to have more information on my HDD and it seems to have SMART features:
